Following the introduction of new, stricter MOT tests, increasing numbers of vehicles have failed with 10 million vehicles having not met the new criteria since its introduction a year ago.
The new MOT test incorporates three new failure categories - minor, major and dangerous with the latter meaning the car is illegal to drive on the road until fixed. Driving a car without a valid MOT could lead to a fine of up to £2,500.
The research carried out by breakdown cover provider Green Flag found a third (33%) of vehicles failed the new test with almost one-in-10 (9%) identified as having a ‘dangerous’ outcome.
More than 30 million MOT tests were undertaken in the past year, 30,488,960 nationwide, and 10,001,293 (33 per cent) failed with 2,817,967 (9%) identified as having dangerous results and 9,095,989 (44%) were found to have major faults.
Most fails were found in the South West (38%), Wales (35%), Scotland (35%), the East Midlands (33%) and the North East (33%). Greater London boasted the highest pass rate (71%) with the East of England (69%), the West Midlands (68%) and the North West (68%) following suit.
Coming into force on 20 May 2018, the new MOT introduced new defect types, stricter emission rules for diesel cars, and some vehicles over 40 years old becoming exempt.
The five areas which are most affected are the different categorisation of defects (dangerous, major and minor); tougher emission rules for diesel cars with a diesel particulate filter (DPF) - a major fault is recorded if the MOT tester can see smoke of any colour coming from the exhaust or if evidence is found that the DPF has been tampered with; equipment tested for the first time under the new MOT includes daytime running lights for vehicles first used from 1 March 2018, under-inflated tyres, contaminated brake fluid and reversing lights on vehicles first used from 1 September 2009, amongst others; the MOT certificate itself has been changed; and cars, vans, motorcycles and other light passenger vehicles won’t need to have an MOT if they’re over 40 years old and have not been substantially changed.
